E sebelisoa haholo bakeng sa liphaephe tsa khatello e tlase. tsamaiso ea litsela.
NPSF-National Standard Oil Dry Seal Thread: Likhoele tsena tse ka hare li sebelisoa bakeng sa kopano e sa koaloang ka likhoele tsa ka ntle tsa NPTF holim'a lisebelisoa tse bonolo kapa li-ductile iron castings.
NPSI - American Standard Dry Seal Intermediate Threads: Likhoele tsena tse ka hare li sebelisetsoa ho kopanya lisebelisoa tse thata kapa tse brittle tse nang le likhoele tse khutšoanyane tsa PTF-SAE, empa li ka boela tsa sebelisoa bakeng sa likopano tse telele tse nang le likhoele tsa ka ntle tsa NPTF.
Taper gauge bakeng sa lisilindara tsa khase
Khoele e khethehileng ea taper bakeng sa li-cylinders tsa khase e sebelisoa bakeng sa ho hokahanya pakeng tsa li-cylinders le li-valve tsa li-cylinders tse sa tšoaneng tsa tšepe (tse kang li-cylinders tsa oksijene, li-cylinders tsa khase, li-cylinders tsa acetylene, joalo-joalo). Botšepehi ba ho notlela le ho tiisoa ha likhokahano tsa likhoele ke eona ntho e ka sehloohong ho netefatsa polokeho ts'ebetsong ea tlhahiso le ts'ebeliso.

Metric trapezoidal thread Tr
Likhoele tsa trapezoidal li sebelisoa haholo ho fetisetsoa (fepa le ho phahamisa) le lisebelisoa tsa ho fetola maemo, 'me li sebelisoa haholo indastering ea mechine. Mamello ea likhoele tsa metric trapezoidal bakeng sa merero e akaretsang e amohela sistimi ea mamello ea likhoele tse tloaelehileng tsa metric, 'me ha ho na boleng bo arohaneng ba mamello bakeng sa liparamente ka bomong joalo ka khoele lead (pitch) le sub-measurement angle. Ka hona, khoele ena ea trapezoidal ha e tšoanelehe bakeng sa likhoele tse nepahetseng tsa phetisetso tse nang le litlhoko tse phahameng tsa ho nepahala ha phetisetso. Khoele e nepahetseng ea phetisetso ea trapezoidal e hloka ho tlatselletsa mamello ea liparamente tsa khoele ka bomong ho latela maemo a kakaretso a khoele ea trapezoidal.
Likhoele tsa trapezoidal le tsona li ka sebelisoa bakeng sa likhokahano tsa ho tiisa. ACME thread le metric serrated thread gauges lia fumaneha
Sistimi ea tlhahlobo ea Amerika bakeng sa likhoele tse tiisang (UN, UNR, UNJ, M le MJ)
Ka lebaka la ho se utloisisane ho hongata, likotsi tse itseng le litlhoko tsa moruo lefapheng la ho lemoha khoele, ho tlisitse mathata a mangata ho amoheloa ha lihlahisoa tsa khoele le ho pata likotsi tse ngata tse patiloeng ho boleng ba lihlahisoa tsa mechine. E le ho khutlisa boemo bona bo sa tsitsang, United States e entse lipatlisiso tse ngata tsa tekheniki mabapi le ho sibolla likhoele, 'me ea sisinya mokhoa oa ho lemoha khoele (standard standard ea ASME) le lintlha tse sa tsitsang tsa 60º thread gauge measure (ASME technical report). United States e etelletse pele lefats'eng ka theknoloji ea ho sebetsa le ho etsa liteko. Nakong e tlang, linaha tse ling lefats'eng li tla ithuta ho tsoa phihlelong ea United States le ho iketsetsa maemo a bona a naha ea tlhahlobo ea likhoele ho ntlafatsa boleng ba lihlahisoa tsa bona. Haeba boholo ba basebetsi ba tekheniki naheng ea rona ba ka ithuta le ho tseba sete ena ea thekenoloji ea tsamaiso ea likhoele kapele kamoo ho ka khonehang, boleng ba lihlahisoa tsa likhoele naheng ea rona bo tla ntlafala ka potlako, 'me re tla tlosa boemo ba tlhahiso ea likhoele tse thata. .
Ho tsoa ho sistimi ea tlhahlobo ea likhoele ea Amerika, o ka ithuta le theknoloji e tsoetseng pele ea ho lokisa likhoele United States. Mohlala, ts'ebeliso ea mahlale a ho lemoha li-gauge tse fapaneng e ka ntlafatsa ho nepahala ha lisebelisoa tsa mochini le lisebelisoa tsa ho seha, le ho sebetsana le likhoele tse haufi le boholo bo nepahetseng ba theory. Ka nako e ts'oanang, bophelo ba lisebelisoa bo tla eketseha.
